FRlNGlN G ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters To all whom it may concern:

Be it knowuthat I, WILLIAM A. ESTAVER of Cambridge, in thecountyofMiddleseX and State of Massachusetts, have invented an Im provement inSewing-Machines, of which the following description, in connection withthe accompanying drawings, is a specification.

This invention has for its object theproduction of a sewing-machineattachment for the manufacture of fringe.

1 have herein shown my invention applied to a Willcox & Gibbssewing-machine; but it may be applied with but slight modification toother well-known sewing-machines. j

In this my invention,wherever a fringe is to be formed upon the cloth orother material from a thread of wool, silk, or cotton,I employ in frontof the presser-foot a vibrating threadguide, which,in its movements atrightangles, or thereabout, to the direction of thefeed movement of thematerial, has the fringingthread carried byitcanght bya fringing-hook,which hookholds the fringing-thread and carries it under the presserwhile the thread-carrier .is moved past the opposite side of thepresser, and on reaching its farthest outward position a heading-fingerengages the fripging-thread near the thread-guide and carriesit forwardunder the prcsser, so that the needle in its nextdescent will cross theneedle-thread over and stitch the fringingthread down upon the material.The head of the fringe islaid by the heading-finger. The heading-fingerand the adjustable fringing-hook are herein shown as carried by the sameshaft.

I am aware thatfringe has been formed upon fabrics on asewing-n1achine,but not by mechanism constructed as herein shown.

Figure 1 represents in front elevation a sewing-machine having myfringing attachmentapplied to it; Fig. 2, a front view thereof; Fig.3, afront elevation of partof the machine with the threadguide anditsco-operating devices in a different position 5 Fig. 4, a sectionaldetail on the dotted line or, Fig.3. Fig.5 represents fringe such asmade by my attachment; and Fig. 6, a sectional detail on the line 3 3Fig. 3.

The drawings represent aregular Willcox & Gibbs sewing-machine,a beingthe needle-bar; a, the vibrating arm to reciprocate the needlebar andits attached eye pointed needle; aflthe Patent No. 251,852, datedJanuary 3, 1882.

Application filed November 19, 1881. (No model.)

usual hook-shaft; a ,the hook c ,th-e usual fourmotioned under-feedingdevice; a the usual presser-foot bar, and a the work or cloth support.

The frame b of the fringing attachment, adjustably connected with thework-support by a thumb-screw, c, has bearings which receive therocker-shaft I), provided at one end with the arm b slotted, as showninFig. 6, to permit the connection with it at a point more or less distantfrom the shaft b of the link d, which embraces the eccentric d onhook-shaft a the connectioubetween the said link "and 'arm I) being madebya thumb nut and screw, 0 0 When the upper end of the link is connectedwith the arm I; nearest the shaft 1) the eccentric d gives to therock-shaft its greatest movement to lengthen the fringe. The rockshaftbhas fixed to its front end the headingfinger e, and outside one of thebearings of the frame I) the said rock-shafthas adjustablyconnected withit by the screw2 the fringing-hook f, having a hooked point, J. Thefringinghook may be adjusted to place its point more or less back of theheading-hook, to thus determine the length of the loops of the fringe gto be formed on the cloth or other material, It, as in Fig.5.

The thread-carrier is composed of a lever, 13, pivoted at F, slotted ati to receive a stud or roller, 11 ,011 the vibrating arm a, by which tovibrate the said thread-carrier, and of adelivcry-piece, t detachablyconnected with the main part of the thread-carrier by a screwffi.

The thread to be used for the fringe y will be led through the eye 4 inthe spring take-up k, and thence into and through the eye 5 of thedelivery-piece t and then to the cloth or material h. The presser-foot Zis extended at'jits inner side toward the fringing-hook, to bear on andprevent the loops of fringe from rising or curling up in the way of theneedle. the thread-guide is in the position shown in Fig. 3 thefringing-hook comes into its most When i forward position toward theoperator, and as 10, draws one part, 12, thereof ful-ly underthepresser-foot, and the other part, 14, but partially underthepresser-foot. J nst before the thread-guide reaches its farthestposition to the left, as in Fig. 1, and the hook f its farthest positionto the rear, the heading-finger e engages the fringing-thread near thethread-guide and is moved backward from the operator, carrying theportion 14 of the loop of fringe being formed back under thepresserfoot, holding the said portion near the outer side of thepresser-foot and stretched under the presserfoot between the said fingerand the hook f,thus measuring off and holdingthe thread in a loop ofthedesired length,while the regular needle of the needlebar a, properlysupplied with thread,descends and crosses its thread over both portions12 14 of the loop, making a stitch, l3, and making the head of thefringe g on the material h.

Thisinexpensiveand simple attachment may be quickly and easily appliedto a sewing-1nachine, and be made to produce a fringe of greater or lesslength.

I claim 1. The thread-guide 1", combined with the fringing-hook f andheading-finger, to carry the fringing-thread backward under thepresser-foot to be stitched in place, substantially as described.

2. The rocker-shaft, its arm, and link d, adjustably attached to it, andthe fringing-hook and heading-finger carried by the said rockshaft,combined with the thread-guide, the needle, needlebar, and presser-foot,under which the fringing-thread is drawn, substantially as described.

3. Therock-shaft b, bearings forit, and means to rock it, combined withthe heading-finger and fringing-hook carried by the said rockshaft, andmade adjustable thereon relatively each to the other, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM A. ESTAVER.
